M2 internship - The main focus of the six-month project will be to improve an existing process & the production of a 3D cellulose packaging, and to provide a specific functionalization during production or in post-treatment. The analysis of the recyclability and the mechanical, structural and physico-chemical characterizations will be performed to understand the influence of the process used. Developing a demonstrator is one of the tasks to be carried out during the internship.
